Question

The following statement calls a function named half, which returns a value that is half that of the argument. (Assume the number variable references a float value.) Write code for the function.

Answer 1

The student requested code for a function named 'half' that returns half the value of a float argument. The Python function 'def half(number): return number / 2.0' fulfills this request.

Step-by-step explanation:

The student has asked for code to be written for a function named half, which returns a value that is half that of its argument, where the argument is a float value. Let's define this function in Python, as it is commonly used in educational contexts:

def half(number):
return number / 2.0

To use this function, you would just call half with the number variable as its argument like this: result = half(number). This function simply takes the argument number, divides it by 2, and returns the result. If number is a float, the result will also be a float representing half of the original value.

Answer 2

The function definition to this question can be given as:

def half (number): #defining a function half and pass a variable number in function parameter

return number/2 #returns value.

data=half(12) #defining variable data that holds function return value

print(data) #print value.

Output:

6.0

Step-by-step explanation:

In the above python program, a function that is half is declare that includes a variable number in the function parameter. Inside the function, the parameter value that is number is divided by 2 and returns its value. In calling time a data variable is defined that holds the function half() value.

In calling time function holds value that is "12" in its parameter and return a value that is "6.0".
